How to read the two-digit display
On the receiver of a wireless kit, a two-digit (7-segment) display is provided.
(1) An indication will be displayed for one hour after power on.
(2) An indication will be displayed for 3.5 seconds after transmitting a “STOP” command from the
wireless remote controller or the operation of the backup button to stop the unit.
(3) An indication appearing in (1) or (2) above will go off as soon as the unit starts operation.
(4) When there are no error records to indicate, addresses of all the connected units are displayed.
(5) When there are some error records remaining, the error records are displayed.
(6) Error records can be cleared by transmitting a "STOP" command from the wireless remote
controller, while the backup button is pressed.

●
Fasten the wiring to the terminal securely and hold the cable securely so as not to apply
unexpected stress on the terminal.
Loose connection or hold will cause abnormal heat generation or fire.
●
Make sure the power supply is turned off when electric wiring work.
Otherwise, electric shock, malfunction and improper running may occur.
●
DO NOT install the wireless kit at the following places in order to avoid malfunction.
●
DO NOT leave the wireless kit without the cover.
In case the cover needs to be detached, protect the receiver with a packaging box or bag
in order to keep it away from water and dust.
(1) Places exposed to direct sunlight
(2) Places near heat devices
(3) High humidity places
(4) Hot surface or cold surface enough to
generate condensation
(5) Places exposed to oil mist or steam directly
(6) Uneven surface
(7) Places affected by the direct airflow of the
AC unit.
(8) Places where the receiver is influenced by
the fluorescent lamp (especially inverter

Correlation between illuminance at the receiver
and reachable area of the signal in a plain view.
The drawing in the right shows the
correlation between the reachable area
of the signal and illuminance at the
receiver when the remote controller is
operated at 1.1m high under the
condition of ceiling height of 2.5m.
When the illuminance becomes double,
the area is narrowed down to two
thirds.
The receivable area of the
signal when the illuminance
at the receiver is 300lux
The receivable area of the
signal when the illuminance at
the receiver is 600lux
③
Installation tips when several receivers are installed close
Minimum distance between the indoor units which can avoid cross communication is 5m
under the condition of 300lux of illuminance at the receiver.
(When no lighting is installed within 1m of the receiver in an ordinary office )
Caution
DO NOT install it on the following places
1. Places exposed to direct sunlight
